Proper speed for a 3" pad on a 6" Griot's

[aquarian]

I am using a rotary adapter so I can use a 3" rotary backing on my 6" Griot's, so it's further away from the machine itself. However I feel that at higher speeds at around 5 or even 4.5 it becomes a little unstable.

What's the appropriate speed that everyone else is using when they have the similar setup? I typically dial to 5 or 5.5 when I am on my 6" using the 6" backing plate. Thanks.

That unstable feeling is normal for a oscillating tool set-up like you have it set up. Make sure the adapter is tightened snugly against the spindle on the Griot's.

I haven't used this set-up in a long time as I'll use the Flex PE14 instead but what you want when trying to remove defects or in other words trying to remove paint is for the pad to be rotating. So try dialing the speed down to the 4-5 setting and as long as you're getting good pad rotation you should be good to go.


Also, mark your backing plate to make it easy for your eyes to see if the pad is rotating or not. Same idea as marking this 5" backing plate.

I tend to drop by 1-1.5. So if I am compounding at 5.5 with 5" backing plate (5.5 inch pad), I'll drop down to 4-4.5 with the 3" backing plate (4 inch pad).

Hey Mike thanks so much for the replies! I also got myself an extender and I think that made the experience a little worse. The 3" rotary backing has a very soft white sponge and maybe that's why I am not used to working with it, as other DA backings are thin and harder. Also with a 3" Lake Country Hydro-Tech the whole setup is super long! :wow:
